Most of the casualties have been reported from Idukki district in central Kerala with 10 deaths. Five members of a family in Adimali in Devikulam Taluk were killed when their house was washed away in a landslide.

Relief camps have been opened in Choornikkara and Kombanad villages as it is anticipated that the release of water will cause water overflow in these areas, PTI quoted Ernakulam district administration officials as saying.

Fatalities in rain-related incidents have also been reported in Kozhikode and Wayanad districts in north Kerala. The active phase of the southwest monsoon has resulted in heavy rainfall over the last 24 hours in these districts.

Kerala State Disaster Management Authority issued a red alert to make necessary preparations for the authorities for evacuation of people in vulnerable areas in case of a water surge. An orange alert was sounded on June 30 at the dam after water level in the reservoir reached 167 metres.
